Viktor Troicki has a few things in common with Novak Djokovic: He's tall, lean, Serbian, and sports a buzz-cut. That's where the comparisons end, and today, as Troicki, ranked No. 42 on the ATP World Tour, let loose on a four-minute gripe aimed at chair umpire Cedric Mourier. The ump had called a ball long that Troicki believed clearly grazed the baseline, and he was having nothing to do with it, even commandeering a cameraman's equipment and ... well, just watch it here.

Ernests Gulbis, Troicki's No. 46-ranked foe from Latvia, went on to win the match, 6-1, 6-1. Despite landing just 53 percent of his first serves, Gulbis cruised in the match, winning 91 percent of his first-serve points (21 of 23). Of course it helps when one strikes shots like this:

It was all so novel in light of Gulbis's own mercurial streak and tirades over time on the tennis court, as evidenced here.

What do you think of Troicki's dust-up? Aside from all the bad points he played, did the Serb make a good point in their lengthy exchange?
